(+)-Benzoylselenopederic acid (1), a left half of (+)-pederin (3), was synthesized stereoselectively based on the Zn(BH4)2 reduction and totalsynthesis of (+)-pederin (3) was accomplished from 1 and the previously synthesized 2.

A highly diastereoselective synthesis of methyl pederate (2) is described. A critical feature of the successful route is the introduction of the key C(7)-stereocenter at the stage of 4 via an enantioselective, syn-selective aldol reaction of aldehyde 5 and the chiral acyl oxazolidinone 6. Aldehyde 5, in turn, was prepared from the readily available aldolderivative 7 via a chelate-controlled reaction
